About this entry

73% of key specs known. Missing: weight, hardening, AR coating, bracelet offered.

The launch model of the revived brand, sold on Kickstarter from 24 January to 24 February 2024 (EUR 740, with EUR 1,050 announced as the retail price) and delivered from mid-June 2024 (Monochrome). Eska's listing calls it the 2024 Kickstarter model, limited to 500 pieces and sold out; it still shows €1,200 (VAT included). Monochrome said casebacks would be individually numbered up to 300. The listing has no spec table (its text is shared with the Black Shark) but names the Seiko NH38 (24 jewels, 3 Hz, 41h) in its movement block, as do Monochrome and The Calibrated Wrist, which says the first batch used the NH38A before the switch to the Sellita SW200-1 (recorded as Amphibian 250 (Sellita SW200)). Case figures (40mm, 46mm lug to lug, 13.5mm high, 250m, screw-down crown, solid caseback, double-domed sapphire, sapphire over the black countdown bezel insert, luminous bezel numerals) are Monochrome's; none of the sources says whether the 13.5mm includes the domed crystal. Lug width is from Eska's 20mm Amphibian strap listings. Steel grade, bezel clicks, AR coating and weight are not published for this batch. Supplied with a black tropic, a sand canvas and a two-piece NATO strap.
